The legs of a right triangle are 10 centimeters and 24 centimeters long. What is the length of the hypotenuse?

22 centimeters
26 centimeters
30 centimeters
34 centimeters

Answers

a² + b² = c²

Where a and b are the legs and c is the hypotenuse

So, plug in 10 for one of the legs and 24 for the other leg

c will be left blank because that is what you are trying to find, the hypotenuse

10² + 24² = c²

100 + 576 = c²

676 = c²

Take the square root of both sides of the equation to isolate c

√676 = √c²

Square of c and the square root cross out on the right

Take the square root of 676

c = 26

So, the length of the hypotenuse is 26 centimeters

Aiden refills three token machines in an arcade. He puts twice the number in machine A as in machine B, and in machine C , he puts 3/4 of what he put in machine A. The total amount of tokens was 18324. How many tokens does each machine have.

Answers

It is a possibility of being 16 or 5/6

Answer:

Machine A has 8144 tokens, machine B has 4072 tokens and machine C has 6108 tokens.

Step-by-step explanation:

Let call: X the number of tokens that machine A has, Y the number of tokens that machine B has and Z the number of tokens that machine C has.

From the sentence: He puts twice the number in machine A as in machine B, we can formulate the equation 1 as:

X = 2*Y

Solving for Y we can write the equation 1 as:

Y = X/2

From the sentence: in machine C , he puts 3/4 of what he put in machine A, we can formulate the equation 2 as:

Z = (3/4)*X

And from the sentence the total amount of tokens was 18324. we can formulate the equation 3 as:

X + Y + Z = 18324

So, if we replace the Y by X/2 and Z by (3/4)X on equation 3 and solve for X, we get:

X + Y + Z = 18324

X + X/2 + (3/4)X = 18324

(9/4)X=18324

X = 18324*(4/9)

X = 8144

Then, replacing this value on equation 1 and 2 to find Y and Z respectively, we get:

Y = X/2 = 8144/2 = 4071

Z = (3/4)*X = (3/4)*4071 = 6108

So, machine A has 8144 tokens, machine B has 4072 tokens and machine C has 6108 tokens.

A banana bread recipe calls for 3/4 cup butter. One tablespoon equals 1/16 cup. How many tablespoons of butter are needed to make the banan bread?

Answers

We're finding the equivalent value to 3/4. So 3/4 would be equal to or equivalent to 12/16. We know this because 12/16 simplified = 3/4. So since 3/4 is equal to 12/16, that means it would take us 12 tablespoons of butter to make the banana bread.

I hope this helps! ^_^

Answer:

There are needed 12 tablespoons of butter to make the banana bread.

Step-by-step explanation:

The recipe calls for 3/4 cups of butter.One tablespoon equals 1/16 cup.

To solve this problem, we just need to use the rule of three. If one tablespoon equals 1/16 cups, how many tablespoons would be 3/4 cups:

[tex]x=\frac{3}{4} \ cups \ \frac{1 \ tablespoon}{\frac{1}{16} \ cups } \\x=\frac{3}{4} \times \frac{16}{1} \ tablespoon\\ x= 12 \ tablespoon[/tex]

Therefore, there are needed 12 tablespoons of butter to make the banana bread.

Two pounds of dried cranberries cost $5.04, 3 pounds of dried cranberries cost $7.56, and 7 pounds of dried cranberries cost $17.64. Write an equation that gives the cost y of x pounds of dried cranberries? Please explain how you got your answer!

Answers

The answer is y=2.52x

The cost equation for dried cranberries is y = 2.52x.

Cost equation:

Using the given data:

2 pounds for $5.04 means each pound costs $5.04/2 = $2.52.

3 pounds for $7.56 means each pound costs $7.56/3 = $2.52.

7 pounds for $17.64 means each pound costs $17.64/7 = $2.52.

Therefore, the cost equation: y = 2.52x where y is the cost and x is the pounds of dried cranberries.

The surface of a trampoline is in the shape of a regular hexagon? Find the measure of each interior angle of the trampoline?

Answers

The sum of all the angles in a regular hexagon will always be 720, so you just have to divide 720 by six (number of angles). That means that each angle will be 120 degrees

The measure of each of the interior angles of the regular hexagon using the Polygon Interior Angle Sum Theorem is 120°.

What is a polygon?

A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.

The sum of the interior angle of a polygon with an 'n' number of sides is given by the formula,

The sum of the interior angle = (n-2)×180°

As it is known that a hexagon has 6 number of sides, therefore, the sum of the interior angles can be written as,

The sum of the interior angle of Hexagon = (6-2)×180° = 720°

Now, the measure of each interior angle = (720°/6) = 120°

Hence, the measure of each of the interior angles of the regular hexagon using the Polygon Interior Angle Sum Theorem is 120°.

y=2x+0.5 I have to solve this using a weird table and then I have to graph it. How?

Answers

you have to choose any input ,plug it in the equation ,solve it and look what is the output.Do that for the rest of the points . when you finish graph your points.

Final answer:

To solve the equation y=2x+0.5, prepare a table of (x, y) values. You plug in sample x values into the equation to obtain corresponding y values. Plot the (x, y) pairs in a graph and draw a line through the points.

Explanation:

To solve the equation y=2x+0.5 and graph it, you need to create a table of (x,y) values.

First, choose some values for x, such as -2, -1, 0, 1, 2. For example, for x = -2, you would plug this value into the equation to find y. Doing the operation y=2*(-2)+0.5, we find that y = -4 + 0.5, so when x = -2, y = -4.5.

Repeat this process for each x value you chose. Once you have a table of values, you can plot these data pairs in a graph, marking the x and y coordinates for each pair. These points should line up and you can draw a line through them. This will be the graph for y = 2x + 0.5.

What is 5/8 divided by 2 7/12?

Answers

before you start the problem, you must always change the mixed number into an improper fraction. In this situation, the mixed number would be 2 7/12. To turn this mixed number into and improper fraction, you multiply 2 by 12, then add 7. The improper fraction would be 31/12. Now, you rewrite the problem using the improper fraction instead of the mixed number. I like to use the technique called, K.C.F. This stands for keep, change, flip. To rewrite this problem again, you rewrite 5/8,( in other terms, you KEEP this fraction the same) CHANGE the division sign into a multiplication sign, and then you FLIP 31/12 to 12/31. Now you simply multiply 5 and 12, which gets you to 60, and then multiply 8 and 31, which gets you to 248. The answer would be 60/248. The final step is to reduce this fraction to 13/62. I hope this helps!

5/8 divided by 27/12 gives fraction 15/62.

To divide 5/8 by 2 7/12, we can convert the mixed number 2 7/12 into an improper fraction.

First, multiply the whole number (2) by the denominator (12) and add the numerator (7) to obtain the new numerator.

= 2 x 12 + 7

= 24 + 7

= 31

The new numerator is 31.

The denominator remains the same, which is 12.

Now we have the division problem:

5/8 ÷ 31/12

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction:

5/8 ÷ 31/12 = 5/8 x 12/31

Now, multiply the numerators and denominators:

= (5 x 12) / (8 x 31)

= 60/248

The fraction 60/248 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4:

= 60/248

= 15/62

Therefore, 5/8 divided by 27/12 gives fraction 15/62.
